Would be a great fight. I've heard Oscar Valdez also wants to fight LSC, and that would be a FOTY type battle. I think Leo would be unphased by Russell's counters and eventually win an entertaining decision. Leo can hit GRJ at a range that is impossible for GRJ to hit him back, so that would force GRJ inside which suits both men well.
Yeah very good fight, to be honest I think GRJ is a much better fighter than LSC but H2H I'm slightly leaning towards LSC, I think GRJ would dominate early but LSC would grind him down slowly starting from the mid rounds.
It's a good match up, and became an even more intriguing fight when Russell Junior brought 10 rounds of gas to a 12 round fight last time out. Santa Cruz may have a small chance at winning now, but Russell jr would be the favorite.
